¹EPIC, European Prospective Investigation into Cancer and Nutrition Potsdam Study; NHS, Nurses' Health Study; WS, Whitehall II Study. P < 0.05 for r > 0.04 or r < −0.04, P < 0.01 for r > 0.06 or r < −0.06, and P < 0.001 for r > 0.07 or r < 0.07. The 95% CIs surrounding all correlation statistics ranged from ±0.033 to ±0.037.

²Defined as the exploratory dietary pattern score derived from reduced rank regression analyses within the Framingham Offspring Study on the basis of food groupings of 1 of the 3 external cohorts.

³Defined as the confirmatory dietary pattern score derived from applying the dietary patterns of the 3 external cohorts to the Framingham Offspring Study population on the basis of food groupings of 1 of the 3 external cohorts.
